无库仑力重整化的质子-质子散射

R. Skibinski, J. Golak, H. Witala, W. Glockle

摘要:

我们数值证明了质子-质子(pp)散射观测值可以直接确定的标准短程方法使用屏蔽pp库仑力没有重整化。在示例中给出了适当的屏蔽半径。我们还数值研究了3维Lippmann-Schwinger(LS)方程的解决方案的屏蔽库仑势单独在大屏蔽半径的限制,并确认分析预测的性能为壳外,半壳和壳库仑t-矩阵。这些3维的解决方案将形成一个新的方法,包括PP库仑相互作用到3 N Faddeev框架的基础。

英文摘要:

We demonstrate numerically that proton-proton (pp) scattering observables can be determined directly by standard short range methods using a screened pp Coulomb force without renormalization. In examples the appropriate screening radii are given. We also numerically investigate solutions of the 3-dimensional Lippmann-Schwinger (LS) equation for a screened Coulomb potential alone in the limit of large screening radii and confirm analytically predicted properties for off-shell, half-shell and on-shell Coulomb t-matrices. These 3-dimensional solutions will form a basis for a novel approach to include the pp Coulomb interaction into the 3N Faddeev framework.
